Tournament management app — Next.js 16 + Supabase + Upstash, free-tier focused.
⚠️ Educational rewrite — not for production use. This codebase is a learning exercise / greenfield rewrite study. It has not been security-audited for real-world deployment, has known launch-gated items (seedocs/development-roadmap.md), and ships without the operational hardening a production tournament platform would require. Use at your own risk; no warranty.
